MAINTENANCE
SPARK PLUG
1. Remove and clean the spark plug (Figure 16).
2. Adjust the spark gap to 0.028 ~0.031 inch (0.6~0.7 mm).
This unit has electronic ignition, which requires no
adjustments.

CHANGING VIBRATOR OIL
1. When changing the vibrator oil, remove the drain plug
(Figure 8).
2. Tip the compactor to drain the oil. Note that the oil will
drain more easily while it is hot.
3. Remember to use only 10W-30 motor oil when
replacing vibrator oil.
CHECKING/REPLACING THE V-BELT AND CLUTCH
After 200 hours of operation, remove the upper belt cover
to check the V-belt tension. Tension is proper if the belt
bends about 10 mm when depressed strongly with finger
between shafts. Loose or worn V-belts reduces power
transmission efficiency, causing weak compaction and
reduces the life of the belt itself.
Replacing the V-belt
Remove the upper and lower belt covers. Engage an offset
wrench (13 mm) or the like to vibrator pulley (lower)
fastening bolt. Engage waste cloth or the like at midway of
V-belt on the left side and while pulling it back strongly,
rotate the offset wrench clockwise so that the V-belt will
come off.
Reinstalling the V-belt
Engage V-belt to lower vibrator pulley and push the V-belt
to left side of upper clutch and, in the same manner as in
removal, rotate offset wrench clockwise so that the V-belt
goes back on.
CAUTION — Vibration Check
Whenever the compactor's vibration becomes weak or
lost during normal operation regardless of operation
hours, check the V-belt and clutch immediately.
WARNING — V-Belt Hazard
NEVER attempt to check the V-belt with the engine
running. Severe injury can occur if your hand (Figure
5) gets caught between the V-belt and the clutch. Always
use safety gloves.
Checking Clutch
Check the clutch simultaneously with V-belt checking. With
belt removed, check outer drum of the clutch for seizure
and "V" groove for wear or damage with your eyes. Clean
the "V" groove as necessary. Wear of lining or shoe should
be checked with running check. If the shoe is worn, power
transmission becomes deficient and slipping will result.
PLATE COMPACTOR STORAGE
For storage of the plate compactor for over 30 days, the
following is required:
„ Drain the fuel tank completely or add STA-BIL to the
fuel.
„ Run the engine until the fuel is completely consumed.
„ Completely drain the oil from the engine crankcase and
follow procedures described in the HONDA engine
Owner's Manual for engine storage.
„ Completely drain the compactor's hydraulic oil from the
vibrating case.
„ Clean entire plate compactor, especially the bottom plate
removing all dirt and foreign matter.
„ Cover plate compactor and engine with plastic covering
or equivalent and store in a clean, dry place.
